TIME-KEEEING CHECK-BOARD.

or DAYTON, oHiof.L

SPECIFICATION forming part of Letters Patent No. 543,603, dated JfrrlyqlSQ.

Application filed March 13, 1893.

To @ZZ whom it may concern:

Be it known that I, FRANK A. PALMER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful ful Improvements in Time-Keeping Check- Boards; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and gures of reference marked thereon, which form a part of this speciication.

My invention relates to improvements in time-keeping check-boards, the features of which will be fully hereinafter described and claimed.

The object of my invention is to give elnploys an opportunity to mark their own time by puncturing a sheet of paper having numbers corresponding to the numbered keys by which said sheet may be perforated.

The object is accomplished by the mechanism illustrated in the accompanying drawings, in which- Figure l is a transverse vertical section of the device on line oc, Fig. 2. Fig. 2 is a front elevation of the same with a portion of the front cut away. Fig. 3 is a perspective View of the locking-plate- Fig. 4 is a side View of the key. Fig. 5 is a portion of a perforated sheet.

Like letters and numerals designate like parts throughout the several views.

The case A is closed by the lid A', and the front wall is perforated,as shown at 8, Fig. 1, and the rear wall is partially so, as shown at 7, same iigure. The lid isV hinged to the top of the case and is secured against opening by the lock J. The cross-pieces B are fixedly attached at their ends to the rear wall of the case, a thin filling being used to provide space for the admission of a sheet of paper between said pieces and said wall. XVhen the cross-pieces B are in place the perforations therein register with holes extending partially through the rear frame, and the said perforations are placed at regular intervals along said cross-pieces. The perforations are for the reception of the several keys D, which are numbered consecuti-vely from one to any desirable Serial No. 465,853. (No model) number, and the several perlorationsv are correspondingly numbered. Within spaces at both ends of the cross-pieces are loosely held the bars F, which have their upper ends bent ata right angle. The rods S extend from side to side and unite these bars. On these rods are suspended the series of locking-plates C, the only use being to elevate said lockingplates, and thereby release the keys. When this device, the frames or bars F, and connecting-wires s s are elevated, the pivotal arms H, secured to the rear wall ot` the frame, maybe pressed under the top ends, and said lockingplates therebyheld out of engagement. Each locking-plate C comprises the flanged top 5 and the notch 6 in the lower end. The anged parts rest on the cross-rod and the notch embraces the neck of the key and is loosely suspended between the front wall and the crosspieces. The metallic keyDcomprises thehead suitably numbered, the shoulder 4, the circular groove 2, and the point 1. The shoulder is to arrest the inner movement of the key,

the groove to engage the locking-plate, and

the pointto penetrate the paper. This key may te made of thin sheet metal, the several parts performing like functions and entering narrow slots instead of round orifices.

At D', Fig. l, one of the keys is shown as it is about to penetrate the paper E and the others are shown fastened in position by the locking-plates. Eisairm piece of paper lined to correspond to the slots or orifices and nurnbered correspondingly to the keys.

The use of the device may be thus described: The proprietor gives to each of his employs a key, which he is required to carry. The employ only has access to the device in the morning before going to work and presses his key into the proper perforation up to the shoulder, thereby penetrating the paper and locking said key securely within the case. To remove the indicating-sheet, the case is unlocked shortly before the close of working hours and the side bars F, with the cross-wires s, carrying the locking-pieces C, are raised, thus releasing the keys D, which allows each workman to take out his individual key, and

thus leaves the sheet free to be withdrawn. A dated sheet is provided for each day and errors are scarcely possible.

Having fully described my invention,what

ICO

I claim, and desirie to secure by Letters Patent, is y l. In e time register, the combination ofthe case provided with cross-bars having perfofrations in alignment with perforations in the rear of said eases; tho side bars with the unitin g carrying ros/ds, the gravity locking plates supported thereon, and the perforating keys for engagementliherewith, substantially as described. Y

2. In :L time register, the combination of the oase provided with transverse bars, and having' perforations therein registering with perforations in the rear of said ease, the Vertical side bars with uniting rods, the locking plates suspended therefrom, the performing keyand the register sheet supported between the said L transverse bers and the rear of tbe ense, subq stautiziily as described.
